Those who claim that E10 fuel is OK for all modern engines, and that gaskets have been suited to this type of fuel for 20 years are seriously misinformed.
Boats with outboard 2 stroke engines are just one of many examples of engines not suited to ethanol at 10%. Cars and trucks use a sealed system which controls emissions and does not allow outside air into the fuel mix except at point of combustion. Boat fuel tanks use an OPEN system with a vent on the side of the hull which allows for pressure in the tank to equalize, thus allowing outside air into the tank where its moisture can mix with the E10 and create phase separation. Then the ethanol looses its octane level and the added water settles on the tank bottom, to later be sucked into carbs or injectors, neither of which is suited nor designed to run on a mix of water and some fuel. Marine tanks have been made out of aluminum, steel, various plastics etc. Water, (in a salt environment) for example, makes for a great environment for electrolysis to occur, thus aluminum tanks often corrode from the inside out, and often most of the boat needs to be dismantled to replace the faulty tank - at great expense and possible risk associated with removing a gas tank built into the boat and intended to live for most of the boat's life without having to be replaced. Newer engines are designed to handle E10 and specifically state that any more than 10% will VOID the manufacturer's warranty. No boat engine 2 or 4 stroke to date is designed to run on E15, to my knowledge.
Old boats with newer four stroke engines, required because of states outlawing two strokes on many waterways, are prone to failing fuel lines not made to E10 specs as well as fuel sender gaskets disintegration, etc.
Lawnmowers, chainsaws, weed eaters are all prone to E10 damage too. Storing fuel for more than a few weeks is a real problem for these engines. Now even Stihl and Echo make their own oils for their 2 stroke engines with an ethanol additive blended into the oil for the gas mix with E10.
Many repair shops for chainsaws, etc. recommend to mix the oil for a two stroke with the highest octane gas available to reduce the chance of lower octane problems with the E10 breakdown over several weeks time. They also say to take any unused gas mix and add it to one's car or truck where it can be burned without causing any problems due to it being diluted in a bigger tank and closed system.
E15 will just exacerbate the above mentioned problems in the marine industry, and to a lesser degree to the auto motive and small engine realm.
